When to do you give up on germing?

I got 10 THC Bomb seeds that have been germing for two weeks now. They sat in my room in a dark place for over a year. I'm going to keep trying to germ these bitches but was curious on how long do you try to germ a seed before you toss it?

3-4 days topps... if they dont crack within 48 hours I start to get leary. what method did you use?

After 5 days, something is wrong.

I saw an old timer say "for stubborn seeds" to polish the seeds with fine sandpaper, or glue sandpaper inside a match box, put the seed in the box and shake it for a long time, to scratch the surface of the seed. Then soak it 12 hours in luke warm water.

damn guess they are screwed. I used the paper towel method. I have had no problem germing B.S. bagseeds using this method.

Try again, soak a few of them first 12 hours in warm water.
